性能测试的原理及其自动化工具的实现

软件组织在对其开发的系统进行性能测试时,可能需要自己编写一些性能测试的工具.但是,性能测试工具的编写是一件复杂的事情,性能测试工具需要满足以下要求：占用系统资源少,可扩展性好,使用性强,能够模拟大规模的用户,能模拟真实的环境等.探讨了在一般的企业级应用中性能测试的原理及基本要求,根据这些需求提出了一个性能测试工具的实现架构,分析了其中的一些关键技术.

Principle of performance test and realization of its automatic tools

When the software organization tests the performance of their systems,some tools need be developed for the performance test.But it is complex to develop a tool for the performance test.It should meet such requirements: need the resource of systems as little as possible,easy to extend,easy to use,simulate large amount users,simulate real environment etc.The principle and the essential requirement in enterprise scale application is discussed,and then a framework and realization method of a tool for testing the performance of applications is put forward,Finally some pivotal techniques in realization the automatic tools are analyzed.
